Looks like a probability pattern or cloud to me.

 

I understand the orbit idea is Rutherford's alternative to the plum pudding idea they had at the time. Whereby the only way they could visualise (say) a negatively charged electron not instantly crashing into the positively charged proton was to have it in orbit, in a similar way as Earth's orbit prevents its gravitational attraction causing it to crash into the Sun.

 

I think the ring shape or pattern you see is a probability cloud, within which an electron (for hydrogen) will be found, within the constraints of Heisenberg's uncertainty. It just happens to be a doughnut shape, which looks like an orbit.

 

The orbit idea is a classical construct, which over time should decay like all classical orbits - end of the universe. It doesn't because it isn't.

An orbital and an orbit are different things.
